摘要：

Coiled tubing (CT) steel is widely used in the oil and gas industry. It is worth noting that CT steels of different grades show similar microstructures but their mechanical and tribological properties can be quite different. The underlying mechanism is unclear, making it difficult to further tailor the CT steel with clear guidelines for specific applications. Using electron work function (EWF) as a probing parameter, we analyzed several typical CT steels having very similar microstructures but showing large differences in their hardness and wear resistance. The EWF analysis indicates that mino...
